System Design with Object Oriented Petri Nets Formalism

The actual trend in the research of system design aims at an efficiency and safety of developing processes as well as at the quality of resulted systems. There were investigated and developed many methodologies of system design based on models -- they are known as Model-Based Design. These methodologies use executable semi-formal models allowing for transformations including code generation in selected language. Nevertheless, the further development or debugging by means of prime models is impossible. This paper brings an outline of our approach to Model-Based Design based on the Object Oriented Petri Nets formalism allowing for clear modeling, the possibility to check correctness by simulation techniques as well as by formal verifications. The model is an executable program valid through all development stages including the target application. The paper depicts the basis of the formalism and used techniques.
